如果測量一個人的細胞數量，事實上只有25%是屬於人體細胞，其餘的75%均由細菌及真菌所據。2664Please respect copyright.ＰＥＮＡＮＡEeV6F2uepv
2664Please respect copyright.ＰＥＮＡＮＡiws8TcOBBP
細菌及真菌可以說是「無處不在」，它們不但寄宿於我們的皮膚外層，亦同時駐紮在我們身體內的腸道及各器官部位，與我們成呈共生關係。2664Please respect copyright.ＰＥＮＡＮＡtoSXvxxQhm

最近有科學家發表學術文章（Ref1)，講述位於汗腺附近的細菌就是腋下異味的其中一個元兇。2664Please respect copyright.ＰＥＮＡＮＡj212CAMO5p

（圖1）我們身體的肝腺大致分為兩種，外分泌汗腺(Eccrine Sweat Glands)及大汗腺2664Please respect copyright.ＰＥＮＡＮＡBfApteqfQP

2664Please respect copyright.ＰＥＮＡＮＡ5iJDk9QW1z
前者接近遍佈全身，不與毛髮連接。後者主要位於腋下、乳頭及私處部位，與毛髮連接。2664Please respect copyright.ＰＥＮＡＮＡZEHRfAKcsB
2664Please respect copyright.ＰＥＮＡＮＡgaPuNRa32l
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2664Please respect copyright.ＰＥＮＡＮＡ3Ak6FI1tst
2664Please respect copyright.ＰＥＮＡＮＡU7zO8VguH1
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2664Please respect copyright.ＰＥＮＡＮＡ3AlVMQ4rqv

（圖2）下列三點為文中所找出的異味散發機制。2664Please respect copyright.ＰＥＮＡＮＡEhXxMlLEAE
2664Please respect copyright.ＰＥＮＡＮＡ4fKFolndgR
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2664Please respect copyright.ＰＥＮＡＮＡwSwwETXZW5
2664Please respect copyright.ＰＥＮＡＮＡXzbik3yJul
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2664Please respect copyright.ＰＥＮＡＮＡkpq1fqa0Va
2664Please respect copyright.ＰＥＮＡＮＡRq5fQtMRsc
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2664Please respect copyright.ＰＥＮＡＮＡNe2qMn61yH
2664Please respect copyright.ＰＥＮＡＮＡ8Hn7Vaqham
換句話說，腋下的異味就是由這些細菌引致而成的。2664Please respect copyright.ＰＥＮＡＮＡCU2jv9ZGyh

（圖3）為作進一步的證實，科學家利用黃金葡萄球菌作對照實驗。2664Please respect copyright.ＰＥＮＡＮＡ1Fa8WPclJV
2664Please respect copyright.ＰＥＮＡＮＡiJBpb1ngvn
他們發現人葡萄球菌的近親黃金葡萄球菌並沒能夠將無味的Cys-Gly-3M3SH消化成為帶有異味的3M3SH。2664Please respect copyright.ＰＥＮＡＮＡqDXWz2T3AL
但是，當把人葡萄球菌其中一隻酵素轉移到黃金葡萄球菌後，無味的Cys-Gly-3M3SH便能夠被消化成為帶有異味的3M3SH，證實異味是由那隻酵素所致。2664Please respect copyright.ＰＥＮＡＮＡr1NdAw8n0T
2664Please respect copyright.ＰＥＮＡＮＡjPW93J2hiE
這隻酵素一直以來並沒有被前人發現，亦即是說，只要能夠研發出抑制那隻酵素的止汗劑的話，腋下的大部份異味亦能得以除去；2664Please respect copyright.ＰＥＮＡＮＡzSvFPUGLqX
2664Please respect copyright.ＰＥＮＡＮＡHP8oNY2aaw
異味的產生，基本上是由硫醇（Thioalcohol)及脂肪酸(Fatty acid)而成。此文章所談及的機制純屬與硫醇的產生有關，沒有觸及脂肪酸那一方面。2664Please respect copyright.ＰＥＮＡＮＡvKAOH3MzaJ
2664Please respect copyright.ＰＥＮＡＮＡoqXaEONCa1
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2664Please respect copyright.ＰＥＮＡＮＡZrg0Yy3n9L
